iss048e045799 (7/22/2016) --- NASA astronaut Jeff Williams poses for a photo with the Tomatosphere-US payload. Image was taken in the Harmony Node 2. Tomatosphere-US provides K-12 classrooms with tomato seeds from space to use in a blind germination study. Participating classes receive two sets of seeds, a control group from the ground and seeds flown in space or subjected to simulated space conditions. When teachers and students submit the results of their experiment, they learn the source of each set of seeds and can compare their data with other classroom experiments around the country.
